I cannot reproduce that issue. What's the underlying hardware machine?
brand: Genuine Intel(R) CPU 000 @ 2.27GHz
model: Westmere-EX
memory: 256G
nr_node: 4
nr_cpu: 80
Ok. I'll try to find something similar. Can please you rerun that test on
that particular configuration with the updated branch?

Hi tglx,

I have tested commit e0b179bc1a ("x86/apic/x2apic: Add conditional IPI shorthands support"), the problem is still exist.
